Codex Windows desktop bug: Computer Use timeouts and shell blocked by sandbox lock failure
index042 · ghdev · 2026-11-08
Issue #60192 on openai/codex reports two failures in the ChatGPT Windows desktop app (26.1103.32239):
- Computer Use getState/getApp requests time out after 30 seconds (reproduced with Grok and Windows Calculator)
- Even a read-only PowerShell Get-Date fails before execution: sandbox provisioning errors with helpersandboxlockfailed and NtCreateFile: Access is denied (os error 5) on the %USERPROFILE%\.codex\.sandbox-bin helper directory
- Failures persist after restart and in fresh local chats
The reporter notes it's environment-specific and doesn't confirm the two failures share a cause.
